Question

What is the angle θ in the triangle below?

Answer 1

Explanation:

using the SOH CAH TOA Rule,

tan 0=opp÷adj

tan 0=9÷4.2

tan 0=2.14

0=tan inverse of 2.14

Answer 2

θ = 64.98310506 degrees (65 degrees rounded to unit)

Explanation:

4.2 * tanθ = 9

4.2 * tanθ/ 4.2 = 9/4.2

tanθ = 2.142857

θ = arctan 2.142857

θ = 64.98310506
